Inguqulelo entsha ye-5.4 ye-Linux kernel isandula ukukhutshwa kwaye njengeenguqulelo zangaphambili, Iimpawu ezininzi ezintsha kunye nophuculo longeziwe kolu guqulelo lutsha lweLinux. Oku indlela yokutshixa iphawulwe eyongezwe kwi-kernel.
Le ndlela yokutshixa qinisa umda phakathi kwe-UID 0 (umsebenzisi weengcambu) kunye ne-kernel. Ngokwenza, xa le ndlela yokutshixa yenziwe, imisebenzi emininzi iyathintelwa. Ii-aplikeshini ezithembele, umzekelo, i-hardware yomgangatho ophantsi okanye ufikelelo lwe-kernel lusenokungasasebenzi. Yiyo loo nto kufuneka isetyenziswe ngononophelo olukhulu okanye kungcono yazi into oyenzayo ngokuyivula.
Olu phawu luye lwaphunyezwa ukuqinisekisa ukuthotyelwa kokhuseleko lwenkqubo ethi, ngokomgaqo, iqinisekise ukuba sinendawo ekhuselekileyo yokuqalisa.
Enye into entsha iyavela yi-virtio-fs, i-FUSE-based virtio driver ukwabelana ngeefayile phakathi kondwendwe kunye nenginginya (yemeko-bume ebonakalayo). Ikwavumela undwendwe ukuba lunyuse uvimba weefayili othunyelwe ngaphandle kumamkeli. Enye yeenzuzo ze-virtio-fs kukuba ithatha ithuba lokusondela komatshini ukuzisa ukusebenza kwe-API kufutshane kwiinkqubo zeefayile zendawo.
Enye into kwiLinux 5.4 yi I-fs-ukunyaniseka ngumaleko wenkxaso kwiinkqubo zefayile ingasetyenziselwa ukukhangela iifayile zomgunyathi, ezifana ne-dm-verity. Nangona kunjalo, isebenza kwiifayile kunezixhobo zokubhloka. Ngelo xesha, Ixhasa inkqubo yefayile ye-ext4 kunye ne-f2fs.
Njengenye into entsha, nayo sinayo i-dm-clone sisixhobo semaphu ekujoliswe kuyo evelisa ikopi enye nganye ukusuka kwisixhobo esikhoyo somthombo wokufunda kuphela ukuya kwisixhobo ekujoliswe kuso sokubhala kuphela.
Ngapha koko, ifaka isixhobo sebhlokhi esibonakalayo esibonisa yonke idatha ngokukhawuleza kwaye iphinda ifunde kwaye ibhale ngokufanelekileyo. Njengemeko yokusetyenziswa, I-dm-clone ingasetyenziselwa ukwenza isixhobo sokuthintela ukufunda kuphela, ukubambezeleka okuphezulu kunye nokubanokubakude kwisixhobo sokuqala, esikhawulezayo, esibhalweyo esenza ukuba ukukhawuleza, ukubambezeleka okuphantsi kwe-I/O. Isixhobo esikhiqiweyo siyabonakala okanye sikhwele ngokukhawuleza kwaye ikopi yesixhobo somthombo kwisixhobo ekusingwa kuso
Kwiinkqubo ezisebenzisa inkqubo yefayile ye EROFS, kufuneka kuqatshelwe ukuba le nguqulo 5.4 hambisa inkqubo yefayile ngaphandle kwendawo yeqonga. Ifakwe okokuqala kwi-Linux 4.9, i-EROFS yinkqubo yefayili yokufunda kuphela ekhaphukhaphu eyenzelwe iimeko ezifuna ukusebenza okuphezulu kokufundwa kuphela okufana ne-firmware kwiselfowuni okanye kwi-Livecds. Ngokufanayo, inkqubo yefayile ye-exFAT ibekwe kwindawo yeqonga.
Sikwanayo kule nguqulo yamva nje yeLinux umqhubi omtsha kunye nerhuluneli ye-cpuidle yokumisa. Iphucula kakhulu ukusebenza kweendwendwe ezifuna ukuvotela undwendwe kwiluphu engasebenziyo.
Ukongeza kolu phuculo, kukho nenkxaso yeemveliso ezine ezintsha ezongeziweyo kumqhubi we-amdgpu. Olu khululo lukwabandakanya izinto zokuqala zokuxhasa iprosesa yemizobo ye-Intel Tiger Lake yexesha elizayo.
Kwicandelo lovavanyo, umqhubi ovulekileyo we-exFAT ophuhliswe yi-Samsung uyongezwa. Ngaphambili, kwakungenakwenzeka ukongeza inkxaso ye-exFAT kwi-kernel ngenxa yamalungelo awodwa omenzi wechiza, kodwa imeko yatshintsha emva kweMicrosoft. iya kupapasha iinkcukacha ezifumaneka esidlangalaleni kwaye uvumele amalungelo awodwa abenzi beexFAT asetyenziswe simahla kwiLinux.
Umqhubi ongezwe kwikernel usekwe kwikhowudi ye-Samsung ephelelwe lixesha (inguqulelo 1.2.9), efuna ukucokiswa kunye nokulungelelaniswa neemfuno zokuyila ikhowudi ye-kernel.
Emva kokongeza umqhubi ophelelwe lixesha, abathanda bathwala i umqhubi omtsha ovela kwi-Samsung (sdFAT 2.x) esetyenziswa kwi-Samsung Android firmware.
Kamva, i-Samsung yagqiba ngokuzimeleyo ukuba iqalise ukukhuthaza umqhubi omtsha we-sdfat kwi-Linux kernel. Ukongeza, iParagon Software ikhutshiwe umqhubi ongomnye ngaphambili ithunyelwe ngepakethe yomqhubi wobunikazi.
Kolunye utshintsho kule nguqulo entsha yeKernel, ezi ziyakwazi ukwaziwa Kule khonkco ilandelayo.
